Question

1. How many milliliters of 13.2 MH.SO, are needed to prepare 600.0 mL of 0.10 M H SOC? (4.5 mL) 2. 1.60 L of an aqueous solution containing 25.00 g of KCl dissolved in pure water is prepared. What is the molarity of the resulting solution? (0.210 M) 3. A solution containing 292 g of Mg(NO3)2 per liter has a density of 1.108 g/mL. What is the molality of the resulting solution? (2.41 m) 4. 12.49 grams of K.SO, are dissolved in 275 grams of water. Calculate the mass percent of potassium sulfate in the resulting solution. (4.344 %) 5. 29.72 grams of NaySO, is dissolved in 323.4 grams of water. Assuming the sodium sulfate completely dissociates, calculate the molality of ions in the resulting solution (1.941 m)
please answer 1-5 and show and explain steps clearly, thank you :)
